T01. aZZfw/l'om itfmay concern Be it. known that we, Pn'rnn and ANGELOBucn onani, citizens of the United States, residing at Swatara Station,in the county of Dauphin, and State of Pennsylvania, have invented newand useful. Improvementsin Stopping Apparatus for liIotor-C'ars, ofwhich the following is a specification.

This invention relates to improvements instopping apparatus for motorcars and has particular application to signal controlled apparatus ofthis character. 7

In carrying" out the present inventiomit is our purpose to provideapparatus of the class, described whereby the propelling power of themotor car Will be cut off and the brakes applied in the event of the caror train passing a danger signal and whereby a signal will he soundedsimultaneously with the cutting oil of the propelling power and theapplication of the brakes.-

It is also our purpose to provide stopping apparatus for motor carswhich will embrace the desired features of simplicity; eflioiency anddurability, which may be installed and maintained at a minimum expenseand which will. operate effectively under all conditions.

With the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts hereinafter set forthin and falling within the scope of the claims.

transverse slot 9 formed, in the base plate 5 is an arm 10 having thelower end thereof connected through the medium of a rod 11 with one limbof a 'bellcrank lever 12 pivoted for swinging movement upon a suitablesupport and having the remaining limb thereof connected through themedium of suitable link mechanism 13 with the signal blade 4 of theadjacent semaphore 2. When the signal blade 4 is actuated to danger po-.sztion motion is transmitted to the arm 10- .through the link mechanism13. bell crank lever 12 and rod 11 and the obstacle plate 8 swung'tovertical or active position. On the other hand, when the signal blade isactuated to clear position, the plate is swung to a horizontal plane orinactive position. In

this embodiment of our invention, we have shown the car carried stoppingmechanism as installed in a steam driven locomotive and in thisconnection we wish it to be understood that this mechanism may beinstalled in locomotives driven by electricity, air, gas, liquid fueland the like without de' parting from the spirit of our invention, Inthe present instance, the car carried stopping mechanism comprises anelectric motor 14 connected in an electric having one end of thearmature shaft thereof projecting outwardly-bf the adjacent extremity ofthe casing. Fast upon the projecting end of the armature shaft is a worm16 meshing with a worm wheel 17 keyed upon a countershafi; 18 journaledin hori positions circuit 15 and" zontally alining; bearings 19 andlying; in a plane parallel vvith'the armature shaft of the motor. I

20 designates the steam main leading from the steam dome of the boilerto the drive cylinders oi the locomotive and located in such main is agate valve 21 normally open and adapted, when closed, to cut of?communication between the steam space of the boiler and the drivecylinders. Connected with the casing of the gate valve 21 and projectingoutwardly therefrom-is a substantially shaped yoke 22 having theinterconnecting; member thereof formed with an opening alining axiallywith the bonnet of the gate valve to receive the stem 23 of the gate.Fixed upon the stem 23 Within the yoke 22 is a disk 2%., whileencircling the stem between the disk 2% and the interconnecting; memberof the yoke is a coiled expansion spring 25 adanted to slide the gate toclosed position. The outer end oi? the stem 23 is bent at right anglesto itseli as at 26 and iournaled in such bent portion is a roller 27normally resting against one face of a sector 28 keyed upon one end ofthe shaft 18 normally disposed in the pat oi movement of the bent end 26oi the stem 23 to hold the latter against sliding movement under theaction of the expansion spring; 25 whereby the gate is held nor madly inopen position. The brake pipe or train line air pipe of the motor car ortrain is indicatul 29 and located in such pipe and normally closed is agate valve 30 havthe end or the stem 31 thereof bent at right angles toitself and formed to provide a tooth 32 meshing with a worm 33 fast uponthe other endot the shaft 18. When the circuit the shaft 18 is revolvedthrough the action of the worm in and worm wheel 17 and in the rotationof the shaft 18 the sector 24 is out of the path of the bent end 28 ofthe stem 23 whereby the spring reacts and slides the sate of the valve21 to closed position, thereby cutting 0d communication between thesteam space of the boiler and the enriine cylinders. Simultaneouslv withthe swin e: of the sector to release the gate the v "e 21 the worm 33 inengagement with the Wo f. 32 the stem 31 of the ate the valve slides thegate of the last- Ill iiZlElllllOllSill valve to open the train line airpipe and so reflects a reduction of pressure therein whereby the brakeswill be applied The shaft 18 also controls connected in series in the acomprises 4; secured to and in- 35 carried by the easnrojectingoutwardly i' n the stem. 31 of the ct 36 lined to and normally en-.

is closed and the'rnotor l4 energized 1 lower end thereor movement bar56 mounter gaging the stationary contact 34 and adapted to ride oil ofsuch stationary contact in the outward movement of the stem 31 under theaction of the Worm 33 to break the circuit 15 of the motor i lsucceeding the opening of the valve 30 and closing of the valve 31whereby the motor will be deenergized.

37 designates a substantially rectangular base plate suitably secured tothe under structure of the motor car and disposed in a horizontal plane.Uprising from the base plate 37 adjacent to one end thereof and spacedapart longitudinally of such plate are bearings 38 and mounted Withinthe bearings and capable of sliding movement therein is a plunger rod39, While upstanding from the base plate 37 adjacent to the opposite endthereof and spaced apart longitudinally of such plate are bearings 4-0in which is mounted for sliding movement a plunger rod ll. Secured tothe confronting ends of the plunger rods 39 and ll are contacts 42connected in series in the circuit 15 and adapted to close such circuitwhen in engagement with each other. lineircling the plunger rod 39between the bearings 38 is coiled expansion spring 43 having'one endabutting; one of the bearings and the opposite end in engagement with ashoulder id formed on the plunger rod adapted to limit the movement ofthe plunger rod under the action of the spring 43. remaining end of theplunger rod 41 is a disk 45 and spaced apart from the adjacent bearing40 and interposed between such disk and bearing is a coiled expansionspring 46, While formed on the plunger at the opposite side of theadjacent bearing 40 is a shoulder 47 adapted to limit the movement theplunger rod 41 under the action of the spring 4:6. Depending from thelower sur- "face of the base plate 3? at the last-men" tioned endthereof are vertical posts 4:3 spaced apart and connected with the lowerextremities of the posts 4% is supporting an opening alinine;

plate 19 formed with end with an opening formed in the adjacent the baseplate 37 and journaled in these lining" openings and capable of rotationherein is a e e-m equipped with an arm o proiecting at right angles tothe shale and lying. normally. in ie plane at right angles to the pathof travel ofthe car. Fast to the upper end of the shalt 50 is aneccetrio 52 erigagrinnthe disk Fined to h shaft 50 immediately abo late49 isa ratchet whee. tne teeth oft-he ratchet "wheel 53 acting to holdthe shai t 50 against tur in one direction. Also fiXQOi the shaft 50above the ratchet Wheel 53 pinion 55 meshing with the teeth oi. l forsliding mo ent l in suitable hoizontally alining guides is: n

Til C Formed on the vertical shaft 50 having the ried by the posts 48, acoiled expansion spring 57 having one end fastened to the rack bar andthe opposite extremity secured to a bracket depending from the baseplate 37, such spring acting through the medium ofthe rack bar 56 andpinion 55 to hold the shaft 50; against turning movement in the oppositedirection.

In practice, when the motor car passes a danger signal, the arm 51impacts against the adjacent edge of the obstacle plate 8 and so rocksthe shaft 50 against the action of the spring 57. In the movement of theshaft 50 under the action of the obstacle plate the dent to theengagement of the contacts 42,

is eliminated.

From the foregoing description taken in the accompanying draw-"connection with V ings, the construction, mode of operation and mannerof employing our invention wi ll be readily apparent. It will be seenthat we have provided automatic stopping mechanism for motor carswhereby the propelling power ofthe motor car will becut 0E and fineourselves to the precise the air brakes applied car running by a dangersignal and wherein the car carried mechanism will be automatically. cutout of service immediately succeeding the cutting off of the propellingpower and application of the brakes. In the present instance, an audiblesignal 58 in the form of a bell is connected in parallel with thecircuit 15 so as to advise the engineer or train crew of the operationof the stopping mechanism. While we have herein shown and describedonepreferred form of our invention by way of illustration, we Wish it tobe understood that we do not limit or condetails of construction hereindescribed and delineated, as modification and variation may be -madewithin the scope, of the claims without departing from the spirit of theinvention.
